me now, nbc news justin correspondent pete williams and michael leiter. pete, ha have you learn about the bombs themselves? >> well, what we're told by authorities, andrea, is that they're crudely made. they appear to have been assembled inside a pressure cooker. it may be some of our younger viewers don't know what that is, but in the olden days when you wanted to make something tender, you put it in this pot with a tight lid on it. and the steam wouldn't escape and you could build up pressure and things cook faster in them. the premicrowave days. inside a pot like this, a pressure cooker is assembled the device. it includes a low-power explosive. something like black or smokeless powder, gun powder, if you will. not a high explosive like dynamite or a plastic explosive or the common tatp, which seems to be the one of voice of terrorists when they build bombs, terror bombs overseas. so it's crudely made, it's set off they believe by some kind of electronic timer. it's carried to the scene, they believe, in some kind of back pack and then just set down before the devices go off. unfor
justice correspondent pete williams has the very latest. >> reporter: investigators have begun the process of recovering tiny pieces of the bombs to learn how they were made. they say it appears the devices were assembled inside pressure cooker pots similar to this one, packed with bbs, ball bearings and nails. pressure cookers have been used for decades in terror bombings. instructions for making them appear on the internet, including just last month in an al qaeda magazine "inspire." investigators say the explosion in boston was smokeless powder, gunpowder like this available at sporting goods stores, not something more powerful like dynamite. and they believed they were carried in the scene in dark nylon bags and set off by timers. the area was checked twice for bombs but there was no security screening. >> because there is unrestricted access to the racecourse, simply because it's 28 miles long, people can come and go and bring items in and out. >> reporter: authorities searched the apartment of a foreign student injured in the blast and seen run ago way but they found nothing and he i
. and for the very latest on the investigation, we're joined now by nbc news justice correspondent pete williams from washington. so, pete, the very latest on the pressure cooker scenario that you're hearing? >> right. as you say, used for decades in terms of building bombs, so that's not going to be an area of inquiry that will immediately lead them in a certain direction, because the instructions, unfortunately, for making these devices are all over internet. just last month, the al qaeda online magazine "inspire" repeated an article that showed how to build pressure cooker bombs. so they've been out there for a long time. the part, the components of this device appear not to be very fancy. in addition to that, there were shrapnel, ball bearings, bbs, from the sound of the doctors you heard at the beginning of your program, apparently nails as well. and then for the explosive basically gun powder, smokeless powder that's commonly available in sporting goods stores. so all these pieces are easily available. some kind of timer as well. then placed in black sacks and put in two different spots. so wha
correspondent pete williams. pete, i'd like to go to you first, given what the president just said coming out and saying it is an act of terror does not come as much of a surprise, given the contours of this. but still something worth remarking on in terms of how the white house is handling this event. >> perhaps so. but this is a case of you know, do as i say, not as i do. or perhaps actions speak louder than words, is what i meant. the very fact that it was announced last night that the fbi was taking the lead in this investigation answered the question. because the fbi has jurisdiction in a case like this only if it's considered an act of terrorism. we crossed that bridge last night. with the words were used or not. in terms of the investigation, let's just clear up a couple of points that were confusing overnight. just two devices, there was a suggestion there were others because so many packages had to be destroyed. there was mixed information about whether any of them campaigned explosives, they did not. sports are starting to learn more about the kproe significance of the bomb. how it
williams joins me now live with the latest. pete, the fact that the fbi is withholding these photos, what is the reason? they've been wanting public help from the beginning of this investigation. but they don't seem to want to put this in public just yet. what's holding them back? >> not yet. i would guess frankly by the end of today it's a likelihood we'll begin to see these pictures. it just depends on whether they can run the string out that they have and identify them on their own. they would prefer to do it that way of course because that way they can preserve some element of surprise here. the problem is they don't know who these people are. they are focused especially on two people now. two young men and they don't know who they are so they what they want to do is find where they are and question them and see what they were up to. they would prefer to do that on their own if they can. so far they have not been able to. i believe they will release these pictures and it may happen today, chuck. >> the fact they would release the pictures, that would be then them saying we need help f
in from our own pete williams. we're working to confirm as many details, again, as possible. several officials say it appears two of these bombs went off near the finish line. again, this happening about two hours after the winners of the marathon. the explosion, itself, taking place right around the time the amateurs were starting to come through. finishing the race. let me take you back to the local coverage, hear more details of what they've been able to uncover. >> temperature of any situation by basically watching, absorbing how fast these police dar cars going. 15 minutes ago the police cars went screaming down the street. shortly after i arrived on the scene, one person said, i can't confirm it, he heard multiple devices have been found. i wanted to wait and so if we could find out more information. indeed, that is true. this area has been cleared out. i'm going to ask jeff, my colleague, to turn around. see more people are being cleared out. let's turn around and look here at st. james street, i should say. st. james street. more people are being cleared out. more emergency v
